I claim as my invention: In a structure of the class described, the combination of a Wheel having a felly, with a tubular annular resilient casing built 10 around and having received therein an annular metal band having a lat cross section tted against the inner face-of the casing Which faces outward and a larger annular resilient band positioned against `the opposite inner face of the casing and a series of lugs, detachably secured to the felly and projecting radially outwardly beyond the inner band to engage and receive the inner portions of the casing for holding the casing on the Wheel, said lugs having their inner ends bent toward and engaging the felly whereby the portions of the casing engaged by their outer ends are compressed between the inner metal band and the lugs.'
